The ordinary double-hung window has sashes that are more or less permanently mounted, and as a result, not

only is the installation or disassembly of the window ren dered a rather laborious and expensive procedure requiring considerable skill on the part of the worker, but also, the washing of the windows is complicated due to the difiiculties of having access to the outer surfaces of the sashes.

The main object of the present invention is to provide a novel sash construction for double-hung windows, so

tes Patent designed that the sashes can be swiftly removed bodily I from their associated frame, and as swiftly remounted within the frame. In this way, repairs or maintenance can be eifected with ease, as for example the sashes can be painted or the panes thereof replaced if broken. Additionally, the washing of the windows is rendered substantially easier while promoting, at the same time, better and more complete cleaning of the sashes.

Another object is to provide sashes that will have the decided advantages noted above, while at the same time being capable of manufacture at a cost little or no greater than that required for sashes not having the mentioned features.

Another object is to provide a sash construction as stated wherein the means for permitting the removal and remounting of the sashes will be used in association with preformed, double-channel strips serving the functions of the usual parting means or strips provided in conventional double-hung window construction.

Another object is to provide means of the character stated that will be formed almost entirely from inexpensive components, particularly adapted for manufacture by mass production methods.

Still another object of importance is to provide means facilitating the removal of the sashes from a window frame which will, at the same time, constitute means for supporting the sashes within the frames and for guiding the sashes during their movement between open and closed positions.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

window frame, said molding having an inner edge portion 23 projecting inwardly of the window frame, to prevent removal of the sashes from the outside of the building structure and, further, to serve as a guide for the slidable movement of the upper sash as best shown in Figure 2. On the inner surface of the molding 22, there is formed a continuous groove 24, receiving tongues formed upon the outer edge surfaces of the side jambs and header, said tongues being designated at 25.

As shown in Figure 4, in the inner surfaces of the side jambs there are formed grooves 28, and mountable in said grooves are guide strips 30, formed of metal by extrusion or by any other suitable process, said guide strips 30 being secured in place by wood screws 32 (see Figure 4) passing through the webs of the respective guide strips and engaged in the side jambs 20. At opposite sides of the webs of the strips, there are formed channels 34, so that said strips are of double-channeled construction, as will be shown to particular advantage in Figures 1 and 4.

Referring to the upper sash 10, at one side this is provided with a locking strip or plate 38 extending the full height of the upper sash. Locking strip 36, as shown in Figure 1, has an outwardly offset outer edge portion 38 projecting outwardly beyond the adjacent side edge of the upper sash. The strip 36 is secured to the sash 10 by means of uniformly spaced screws 40,passing through short slots 42 that extend transversely of the strip36 The strip 36, thus, is mounted for lateral displacement, between a locking position in which the edge portion38 projects outwardly beyond the side of the sash in the man ner shown in Figure 5, and an unlocking or retracted position in which the outer longitudinal edge of strip 36 is flush with the adjacent side edge of the sashll). I l

In Figure 1, the sashes are seen from theinside of the building, and it will be noted that the combined mounting, locking and weather stripping plates are on the inner side of the upper sash and on the outer side of the lower sash. Further, the upper sash has a movable plate along its right hand side rail while the lower sash has an'identically but oppositely formed movable plate along its left hand side edge. The upper sash 10 has a stationary plate along its left hand side edge and the lower sash 12 has a stationary plate along its right hand side edge..--

Spaced longitudinally of the plate 36 are two short longitudinal slots 44. These provide cam slots receiving eccentric lugs 46 projecting inwardly of the building from disc-shaped heads 48 of pins 50 rotating in through openings 51 of the upper sash. The other ends of the pins are exposed to the inside of the building and are formed with kerfs for receiving a screw driver bit. Other means facilitating rotation of the pinsyas for example'levers or handles, could be provided on the pins.

The outer edge portion of plate 36 is extendable to its Figure 5 position into the outer channel 34 of guide strip 30, by rotating pins 50 in one direction, and is retractable from the channel to its Figure 6 position by rotating the pins in an opposite direction. This is effected by the motion-translating linkage constituted by the. pins 50, eccentric lugs 30. andslots 44, adapted to convert rotary motion of -the pins into lateral sliding movement of plate 36 on screws 40 between opposite extreme positions determined by the length of slots 42.

genome .On the opposite side edge of the sash 16 there isfixedly mounted a plate 52 secured by screws 54 to the sash with its outer longitudinal ::edge portion projecting out wardly strain the sash {into lithe :outer ."chan-nel 5.4 lnf rthe .other guide :strip 136.

They-fnrthersenve, .in cooperation with ,the .guide strips, in Weatherstripping rthe window. In addition, they eliminate .theaneedrfor .sash'; cords and weights, due to the fact that with themovable ;-plate partially retracted, the sash can ,besraisedror flowered and then looked in :the position to which it is :moved, -;by rotation of -.the ,pins ssuffieiently to .tully extend ithe movable plate 36 .and..-fric.tiona1ly zbindtthe :samea-in .-its associated channel The lower :sashhas almovable platejfisidentical-hut opposite to the plate .fifimounted, .as previously :noted, :on the outsidepf the. lower sash along the leitthand side rail thereof, and adjustahle laterally .by pins 58.;similar to pins 50; On-the rightlhandsiderail, the .lowensash has a stationary plate 60 analogousto plate 52-.of-the upper .sash.

The construction permits the sashes to lac-removed with maximum :ease and speed, for '1 cleaning, painting-tor any other purpose.

Qonversionmf in conventional, double-hung window :to .a 'window having removable, weather-stripped sashes is etfectedl-easily-and speedily eby .first removing the usual parting .strips ;of the Side jambs and thenmounting in the grooves 28, left by removal of the parting strips, the doubleaehanneled'guide strips 30.
